EUGENE DECOLLOGNE, OF PARIS, FRANCE.

FEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 428,768, dated May27,1890. Application filed February 18, 1890- fierial No. 340,973. (Nomodel.) Patented in England December 19, 1889, No 20,455

and without causing an obstruction or stoppage in the distributingparts.

The accompanying drawings clearly illustrate the arrangement of thedifferent parts of a distributer constructed according to thisinvention, and in said drawings Figure 1 is a side elevation, and Fig. 2a plan view, of the distributer.

The two fluted or grooved distributing-r011 ers b and c are fixed uponthe mill-hopper a.

Upon the shafts b and c of these rollers are-- secured the toothedwheels d and e. The tooth-wheel e, fixed upon the shaft of the smallerdistributing-roller c, is provided with eight times the number of teethof the toothwheel d on the shaft of the large distributingroller,whichreceivesits motion from the driving-pulley f, secured upon the shaft 1)outside of the frame which supports the difierent distributing parts.

The ends of the shafts I) and c are supported in bearings. The bearingsg of the shaft 1) are fixed, while the bearings h of the shaft 0 areadjustable, and can be moved upon the apparatus by operating thehandwheel 7;, which is secured on the screw Zturning in the fixed nut m.

By rotating the hand-wheel k the space between the small adjustableroller 0 and the large distributing-roller b may be increased ordiminished according to the direction of such rotation, and the deliveryof the distributer may thus be regulated.

It will be understood that instead of giving the wheel 6 a number ofteeth equal to eight times the number of teeth of the wheel (Z therelative number of these teeth may be varied, as desired, so as to varythe speed of the smaller roller 0, and thereby vary the quantity ofmaterial delivered.

- I claim In a feed-regulator for grinding-mills, the combination, withthe hopper, of shafts passing through the hopper and the sides thereof,one of said shafts being mounted in fixed bearings and the other inadjustable bearings upon the outside of the hopper, whereby the lattershaft maybe adjusted toward and from the fixed shaft, grooved rollersmounted upon said shafts, the roller upon the fixed shaft being of largediameter and the roller upon the adjustable shaft of relatively smalldiameter, a gear-wheel mounted upon one end of the fixed shaft, and agear-wheel of relatively large diameter mounted upon one end of theadjustable shaft and gearing with the other geal wheel, and means forrotating one of said shafts, as and for the purpose specified.

In testimony whereof I have hereto set my hand in the presence of thesubscribing witnesses.

EUGENE DECOLLOGNE.
